adapted to be connected by means of a link {shoulders 66' of the-bars 51-52, 72-73- 74-7 indicate -arms mounted upon the squared shaft? 49 between the bars 51-52, each of said arms being mounted upon said shaft by means of 'a hub-portion 76 which extends from one to the other of thebars 51-52 centering the arm betweensaid bars and spacing the arm a distance therefrom at each side As bestshown in Fig. 7, the arms 72-73-74-75 are spaced about the shaft 49' at an angle to each other so that when the shaft is turned in a clockwise direction as shown in Fig. 7 the arms are brought successively into operative position. The arm 72 of the raising means-for the foremost plow is adapted to stand normally in the position of-thearm shown in Fig. 6, lightly in contact with the roller 59 of its pair of'levers55-56. Upon airotation of the shaft i9 in clockwise direction as shown in Figs. 6 and the arm 72 causes the roller 59 of the" levers 55-56 by which the foremost plo'w is raised to move upward, swin ing said levers55-56 upward and forward, starting the operation of raising the foremost plow. Shortly thereafter the arm 73 is brought in contact with the roller 59 of the next succeeding pair of levers 55-56, starting the operationof raising the second plow. successively thereafter the remaining lifting arms are brought into contact with the rollers 59.nf the remaining pairs of. levers 55-56'whereby the plows are raised in succession, the foremost plow first and the rearmostplpw last, the, arrangement of the arms 72, 73, 74, 75, etc, being such that all of the-plows are raised at sub-.

stantially the same point relative to the forward movement of the plow,'-that 1s.to say at a line at right angles to the progress of the plow; As each plow reaches itsuppermost position the latch 61 engagesthe corresponding shoulder 66 looking all of the plows in raised posit-ion. Coming now to the means for releasing the plows to permit them to drop successively on a line at right angles to the for-- ward movement of the plow, 77 indicates ashaft revolubly mounted in the'framework in advance of the shaft 49.- As best shown.

in Fig. 8, 7S-79-80-81 indicate arms mounted upon the shaft 77 at an angleto each other, the angle between successive.

arms 78-79-80-81 corresponding to the angle between the arms 72-73-74-75 upon the shaft 49. Each of the arms 78- "9-80-81 is mounted between two of the bars 51-52 and is provided atits free end with 'a roller 82. The roller 82 of the arm 78 .normally stands substantially in contact with the heel of the latch-lever 61 by which "tion,-that is to say, of course, when the levers 55-56 are in their foremost position as illustrated in Fi 2. lVith all of the plows held in raise position by means of the latches 61 and with the levers in position to permit the lowering of the plowbeams a rotation of the shaft 77 in counterclockwise direction causes the roller 82 of the arm 78 to release the latch 61 of the first pair of levers -56 permitting the foremost plow to drop into operative position. Shortly thereafter as the shaft 77 continues to rotate the roller 82 of the arm 7 9 releases the latch 61 of the second pair' of levers 55-56 permitting the second plow to drop, and at intervals thereafter each of the plows is likewise released, the arrangement of the arms 78, 79, 80, 81, etc, being such that as the shaft 77 continues to rotate in counterclockwise direction as driven by the flu-ward progress of the plow, the plow-shares 28 drop at the same relative point,-that is to say at a line at right angles to the progress of the plow.

Referring to Fig. 5 which shows in detail one of the arms 72-73-74-75, 83 indicates a br'acket formed with and extending from one side of the hub 76, said bracket comprising a main web 84 and two flanges 84:" at opposite sides of said web 84. 85 indicates a block inserted in said bracket 83, said block having a curved exterior surface along which the roller 59 is adapted to roll as the arm forces the levers 55-56 upward and forward. 86 indicates a set-screw mounted in the block 85 adapted to limit the movement of said block toward the hub/76. 87 indicates a set-crew mounted in the block 85 and passing through a slot 88 in the web 84, said set-screw 87 being adapted to clamp theblock 85 in adjusted position in said bracket 83. As best shown in Fig. 6 each of the arms 78-79-80-81 is cut out at its central portion for the reception of the roller 82 which is revolubly mounted thereon by means of a pin 89.

' 'Coming now to themeans'for driving the shafts 49 and 77 as desired. the shaft 49in clockwise direction and the shaft 77 in counterclockwise direction. as shown in Figs. 2 and 3, 9O indicates a drive-wheel mounted upon-an axle 91 carried by the frame 20. 92 indicates-a sprocket-gear mounted concentricallj' with the wheel 90 and adapted to rotate therewith; 93 indicates a sprocketchain connecting sprocket-gear 92 with sprocket-teeth 94 mounted upon the periphery of -'the clutch-wheel 95 revolubly mounted by mejansof a'huh 96 upon the rounded end of the shaft 49. As best shown in Fig. 12 the clutch-wheel 95 comprises two clutch members 979 198, -each of which con-' sists" of a circumferential I flange evenly grooved on ts nner periphery.

99 indicates'a collar squared in cross-section secured in position upon the squared shaft 49 by means of a set-screw 100.

101 indicates abracket (see Figs. 10 and 1 1-) formed with the collar 99, one end of said bracket being cutout in circular form to receive a circular roller as hereinafter described.

102 indicates an arm pivotally mounted. by means of a pin 103 upon the bracket. 101.

104 indicates a roller revolubly mount-ed upon the arm 102 adapted normally to pass into engagement with one of the grooves of the clutch member 97, as best shown in Fig. 14, such engagement being ettectcd through the medium of a spring 105 attached to one end of the arm 102 and to the bracket 101. 106 indicates a lever pivotally mounted by means of a bracket 107 upon the rounded end of the shaft 77, said lever being normally held against swinging in a clockwise direction asshown in Fig. 10 by means of a spring 108 mounted as hereinafter described. I

' 109 indicates a roller revolubly mounted upon the upper end of the bracket 107. adapted' to engage the notched or rounded out; end of the bracket 101. As best shown in Fig. 10 when the lever 106 is held by the spring 108 in its extreme turned position the roller 109 serves not only to engage the end of the bracket 101 but also engages the end of the arm 102 holding said arm turned upon its pivot 103 against the action ofthe spring 105 so as to hold the roller 104 out of engagement with the grooves in the inner periphery of the clutch member 97. \Vlien.

- causes the shaft- 49 also to rotate in clock-- wise direction in said figure as will be readily understood. Vhcn the-bracket'101 has been turned out of the position in which the roller1109 is adapted to engage said bracket the leyer 106 is held against undue rotation in counterclockwise direction upon the shaft 77 by means of a lug 110 on the b5 bracket 107 comingin contactwith the transverse frame-bar 48. \Vhen the bracket 101 has been given a complete rotation with which engagement the arm 102- is swung against the action of the spring rocking gear 112 through the medium of gears 1let115 interposed therebetween, said ears 111--115 being mounted upon stub-s iafts '117, respectively, suitably mounted in the frame-bar 50. As .will be seen from Fig. 9 the channel-iron frame-bar 50 incloscs the gears 114=115113 servingas a housing for the protection of said parts, this arrangement serving also to materially economize space without sacrificing strength.

118 indicates a bracket (see Figs. lland 13) formed with the sleeve 111, the'outer end of said bracket being rounded out for the reception of a roller 119' hereinafter re- ,ferred to.

120 indicates an arm pivota'lly mounted by means of a pin 121 upon the bracket 118. said arm 120 having revolubly mounted upon it a roller 122 adapted normally to engageone of the peripheral grooves of the clutch member 98. such normal engagement bctween the roller 122 and the clutch member 98 being secured by means of a spring 121) connecting one end of the arm 120 to the bracket- 118.

121 indicates a lever pivotally mounted by means of a bracket upon the rounded end of the shaft 77. The bracket 125 has the roller 119' revolubly mounted upon it,.

said roller while in engagement with -the rounded end of said, bracket 118 serving to hold the arm 120 turned in clockwise direction relative to the bracket 118 in Fig. 11 against the action of the spring 123 holding the roller 122 out ofcontactwith the grooved clutch member 98 the lever 124 being normally held in the position shown in said Fig. 11 through the medium of the spring 108 as hereinafter described. As will be readily understood, with the clutch-wheel 95 beingrotated in counterclockwise direction in Fig. 11 by its connection with the drive-wheel 90, and with the parts in the position shown in said figure, the shaft 77 is not in rotation. \Vhen the lever 124,. however. has been given a stroke in counterclockwise direction in said figure so-as to free the roller 119 from the bracket 118 and the arm 120'the roller 122 is brought. by the spring 123 into engagement with one of the grooves of the clutch member 98'causing the bracket 120 and the sleeve 111 to rotatewith said clutch-wheel in counterclockwise direction in said figure, serving to drive the shaft 77 in clockwise direction in said figure. When the bracket 118 has been moved out of position in which it may be. engaged by'the roller 119 the lever 121 is held against undue rotation in clockwise direction in Fig. 11 by means of the lug 126 on -the bracket 123 being brought in contact with the transverse frame-bar. \Yhen the bracket 118 makes substantially a complete rotation with the clutch-wheel 95 the roller 119 carried by the lever 124 rides up the forward edge of the bracket 1183s said bracket is rotated and assumes again engagement with the rounded out or recessed end of said bracket, forcing the arm 120 in clockwise direction in F ig. 11 against tlit action of the spr ng 123,-freemg the roller 122 from engagement with the groove of the clutch membe'r 98.

127-?128 vin dicate cords attached at their rear ends to'the levers 1'06124, respectively.

It will be understoodthatby a forward pull upon a1sm-(1.12 7 by an operator the clutch memberfiI- beeoinesoperative to cause onecomplete rotation of the shaft- 49- in clockwise-direction in Figs=2 time causing the pleas to be success vely raised if before the actna tion of the lever 106 by the cord 127 the plows werein lowered position. :It will be understood thatwhen ,the plows are held .in raised position a. forward =p[ull upon the cord 12S :serves topperatively connect the.

clutch-wheel 95. througlrtheclutch member 98 with the shaft '4'? to cause a complete rota,- tion of said shaft in counterclockwisedirection in Figs. Q'and 3 for releasing the plows successively from raised position as herein.- before described] 129 indicates a cross-bar extending from one. to the other of the brackets 107 125 of theI levers106..l24, with theends ofsaid cr'oss bar gextending through. suitable openingsin. the lower ends of said brackets.

130 indicates a bracket extending forward from the transverse .fra'me-ban lsopposite ,the middle pointof the cross-bar 129,.the

spring -10 8 before referred to being connected at-its rear endto the middle point of the.

cross-bar 129 and .at 'its' other end to-the frontend of the bracket 130.

By the expedient. of mounting the arms- 72-.73574; +75 between the ends of the levers 55-:56 when in their rearmost position,

I secure aconst-ruction in which the roller 59 during the'firstporticn'of the raisingop. eration, at which time the greatest power is requiredfer starting theplow from the. ground, contacts its arm 7273,- -.'Z4= 'Z5 at substantially the same pointquite close to the axis of rotation of the shaft 49 the action being almost purelya lifting action with scarcely any friction. Afterthe plow.

is practically clear of the ground and .the

heavy lifting has been accomplished theroller 59 gradually approaches the end of the curved operative face of the lifting arm with the consequent more rapid turning of the levers 55--56.
